chine for making railway and other largespikes; and it consists in thecertain details of construction and combination of parts, asV

will be fully described hereinafter.

In the accompanying drawings, Figure l is a central side sectionalelevation of my improved spike-making machine, the same beingconstructed and arranged in accordance with my invention. Fig. 2 is aside elevation of the same, a portion of the frame of which is brokenaway. machine. Fig. 4 is an end View of a portion of the machine,showing the separator-frame and the side grip. Fig. 5 is an end view ofthe kicker or device for knocking out the finished spike from itsposition between the gripping-dies. Fig. 6 is a detailed view of aportion of the feeding mechanism, the outer plate of thesupporting-frame 4being removed in order to better show the pawl andratchet.

To construct a machine for making railway and other large spikes inaccordance with my inventiom'l provide a frame l, of a suitable size andform of construction, and mount therein a drive-shaft 2, having afly-wheel 3 and connected to a means for giving the said shaft arotatable movement. Formed upon this drive-shaft 2 is a cam 6, adaptedto operate a clamping -lever 4, the same being mounted upon a shaft 5 inbearings 9 and provided With the ordinary means or adjustmentplates lO,arranged at each end of the shaft, and with springs l1' to relieve thelever 4 should a double spike" enter between the clamping-dies. Arrangedin the forward end of the lever 4 is a removable clamping-die 7, which,in connection with a stationary die 12 and moving die 8, will hold thespike 28 while the same is being headed This moving die 8 is mounted,upon a shaft 13, arranged Fig. 3 is a plan view of the in bearings atthe base of the frame l, and the said die formed with anoutwardly-projecting portion 14, which extends la short distance beyondthe side of the frame. Pivoted to a shaft 17 at one side of the frame 1and operated by a cam 18, attached to the-driveshaft 2, is a lever 15,which is connected by a toggle-pin 16 to the( outwardly-extending arm 14of the moving die 8 in a manner that willoperate'the said moving die 8toward and away from the stationary die l2 to aid the die 7 in clampingthe spike While forming the head of the same.

'The head of the spike is formed by the heading-die, which consists of astout bar 20, capable of a limited forward movement in suitableguideways 2l by means of a cam 19 formed on the drive-shaft 2, and thesaid bar 2O being fitted with a headingdie 23 at its forward end and thedie and bar recovered or brought back by a suitable spring 22, one

the one knife registering with the other and formed toshear through thebar 30, from which the spikes are formed, and at the same time press achisel-point upon the same.

These disks 26 and 26' are mounted on shafts 43 and 43', the upper shaftof which is ar-l ranged in sliding bearings, which are held in positionby set-screws 31. Each of these shafts 43 43'is fitted with a gear-wheel38 38',

the one meshing with the other in order that the cutters may revolve inunison, and' connected to the upper shaft 43 is acrank 39, a ratchet 40,and spring-actuated pawl 41. This crank 39 is connected bymeans of a rod37 to a crank 36, secured to a shaft 17', arranged across the frame.Attached to the other end of this last-mentioned shaft 17' is a slottedcrank 30, in which a sliding block 32 is arranged, and the position ofthe said block regulated by means of a screw 33 in a manner that thesaid sliding block 32 may be IOO moved toward or away from the shaft 17'for the purpose of adjustment to regulate the throw of the crank 39,connected to shaft of the disks in which the cutters are mounted. Thissliding block 32 is connected by a pitman 34 to the disk 18, forming apart of the cam for operating the lower clampinglever 15. The object ofthis last-described mechanism is to rotate the disks 26 and 26 a limiteddistance at each revolution of the drive-shaft 2, the said distancebeing regulated by the position of the sliding block. This movement ofthe disks feeds the bar 30 forward the length of one spike.

The knives 27 and 27 not being able to entirely shear or separate thebar 30 will leave a thin web joining the said bar with the spike 28, asshown in Fig. 1 of the drawings. Therefore it is necessary to provide ameans for separating the two. This means consists of two bars 54,arranged in bearings or slides 46, the ends of which bear against theoscillating frame 25 and against small cams 55, formed in thedrive-shaft 2 in a manner that at each revolution of the said shaft thebars will move forward, pushing the oscillating frame 25 and tearing orseparating the spike from the bar. The oscillating frame 25 is recoveredor brought back to position by a spring 60. (See Fig. 2 of thedrawings.)

To knock the finished spike 28 from between the gripping-dies, a rod orbar is arranged in bearings at one side of the frame 1, the said rod 45having a portion 47 bent at an angle adapted to contact with aprojection 44 on the flywheel of the machine and the other end 47 bentinwardly to a position over the spike 28.

. At each revolution of the fly-wheel the end 47 of the bar 45 is movedupward, thereby moving the inner end 47 down, moving the spike free ofthe gripping-dies and permitting the same to fall beneath the machine.

In operation the bar 30, from which the spikes are to be formed, is fedbetween the disks 26 26', the said disks being rotated a distancecorresponding with the length of the spike by means of the connectedmechanism with the drive-shaft 2. This motion is derived from the disk18, connected to the adjusting-crank 30, and by means of its shaft 17motion is given to the crank 36 on the opposite side of the machine andfrom this crank 36 by the connecting-bar 37 to the crank 39, giving thesame a back-and-forward or oscillating movement. This movement of thelast-mentioned crank 39, together with the pawl 41 and ratchet-wheel 40,moves the bar 30 a predetermined distance into the machine and at thesame time the cutters 27 and 27', operating to form the point of thesaid spike. The bar 30, not being entirely separated from the piece 29,will shove the same forward upon the next action of the ratchet-wheel40, placing the said piece between the grippingies 8 and 12. These dies8 and 12, together the top die, will hold the blank 26 rmly,

while the heading-die 23 forms the head of the spike 28 by its forwardmovement. The spike now being formed, the cams 55 move the two bars 54forward, slightly turning the oscillating frame 25 upon its shaft,thereby separating the finished spike 28 from the blank 29 following. Atthis time the gripping-dies 8, 12, and 7 open and the kicker 47 operatesto throw the spike free from the gripper-dies.

Various slight modifications and changes may be made in the details ofconstruction without departing from the spirit of the invention.Therefore I do not confine myself to the exact construction shown anddescribed.
